It is no secret for many that trams were already in the 1800s, however, judging by the footage of those times, it is not clear what set them in motion.
There were trams that were steamed. But in the newsreels of that period, other trams run, which are not on a pair and not on wires. There are photographs in which trams are pulled by horses, but why make such a complex structure for a horse?
There are photos and videos of trams on their own. What set them in motion? Trams traveled all over the world and everywhere according to the same principle. How could they ride? And we have three options for an answer. Or:
- Wireless electricity;
- On the rail on the ground;
- Cable drive between rails;
Rope type is the official option. There are still cable trams in San Francisco, today there are 2 lines left for the entertainment of tourists, the rest have been removed. The cable moves, and the tram is hooked on and uncoupled during stops.
In many photos of those times and even on the video, you can often see that there is another "channel" between the rails in the center. At the expense of which he can work.
But not everywhere there is a rail in the middle. In the newsreel, two trams go one after the other, how, in this case, to ensure the tension of the cable even with a straight line, not to mention the turns? Moreover, the rails run in a straight line. That is, it turns out that there were trams that moved with a cable, but there were others.
Promotional video:
By the way, there were quite a few such cars themselves, there are numbers over 4 thousand.
Steel began to be cast in production by the 1870s, and then as the first attempts, that is, it turns out that they did not really know how to work with steel, but over 4 thousand trams were already made and the rails were also laid.
Conductive rails are too dangerous for open areas, this is not a subway for you.
Perhaps these are wireless electricity technologies that were used and worked on the principles of Tesla coils. But this was not beneficial to the elite, so everything was confiscated. It's hard to believe in this, because we don't have such technologies, but this does not mean that they did not exist before.
Perhaps earlier they used electricity from the air, there is such a theory in favor of which many facts have already been found, such as, for example, photographs.
